British Airways has confirmed a data breach that exposed personal details and credit-card numbers of up to 380,000 customers and lasted for more than two weeks.
In a statement released by British Airways on Thursday, customers booking flights on its website (ba.com) and British Airways mobile app between late 21 August and 5 September were compromised.
The airline advised customers who made bookings during that 15 days period and believe they may have been affected by this incident to "contact their banks or credit card providers and follow their recommended advice."

The company also said that saved cards on its website and mobile app are not compromised in the breach. Only cards that have been used by you to make booking payments during the affected period are stolen.
"We are investigating, as a matter of urgency, the theft of customer data from our website and our mobile app," the company said in a statement. "The stolen data did not include travel or passport details."
